Be it known thatI, ROBERT STA NLFlY BOLGERfa citizen of the United States, residing at New. York city, New York, have mvented certain new. and useful Improve- "mentsin Improved Stencils and Frames, of which the following is a clear, full, and exact description.

The objeetof'this invention-is to provide a rigid and substantial stencil, frame, preferablyof metal, with a removable stencil card in the form of 'a' slieetof ilexible and relat ively-thin material.

To use aflexible stencil sheet is obviously advantageous in saving material, in enabling "oneft'o get better'and cleaner stencil letters and also stencil letteiswhich will not clog withink as quicklyor with the ill effects ofa thick card Whensuchis used. such stencil sheets have been used heretofore but each necessarily bad its own attached and indi -vidual frame to whichit was glued. Such framewas'g enerallymade of stiff card board.

and [would warp to a greater orless extent. The frame used by me in this invention is rigid, preferably metal, and hence no warplng occursm A According to my invention I so form my frame and sheet as toallow one fr me to be used "indefinitely and any num-" ber of different sheets'used with the same .frame by merely slipping the sheet desired into the frame. In order to do this I prowide means for holding the sheet taut transversely of the frame, Without unduly preventing its removal longitudinally.

By flexible as used in this application .I mean likethin papen'which may be folded 'to produce a crease and not crack at the fold. -I use the term to distinguish from strawboard or cardboard usually used for this pur- I pose, which it is my aim to supplant by thin paper of little greater thickness but preferab y of greater strength than that, upon wlnch ,Letters Patent are printed; Cardboard is too thick to produce the best stencil openings and it is too difficult to properly and cheaply perforate it. The thin flexible paper used by me is cheap at first cost, cheap to perforate, does not-wear out the perforating type and produces the best possible ef- All this has been recogaperstencils have been glued -onto card oard frames from which they were not detachable without destruction, and they were'apt to warp out of aplan of my improved frame;

shape, or they have depended on their own semi-rigidity in openframes from which'they are often accidentally detached by being bent out of shape at the center. -My invention will be particularly pointed out in the claims.

In the accompanying drawi s, Figure 1 is t1on of the same on line 2-2 g. l with ig 2 is a sec-.

sheet in place; Fig. 3 is a similar. sectional 5 view'of a modifiedform of frame.

As shown in the drawings, the stencil frame is formed of a back plate 1 with a central-openin "2'. Onitslongitudinalsides3 3 theedge o the frame is turned in; as at 4,

substantially parallel with the back -'plate"1,:-

and in thepreferred formpf Figs. 1' andf2 the portion 4 is again turned towards the bight;

formed in the frame by-the first fold produces a tongue portion-5 in the bight. At one end of the frame I, prefer to. fold the metal or material to form a pocket or abutment-6 into which the'end of the s'heetmay project for the longitudinal ositioning ofthe same, and at'the other end refer to forma slight turned-over edge or a utment '7 over which the sheet may be slipped and when in place its end caused to lie against the .inner side of the same. I p'referthat the turned-in sides do not reach to the end of the frame for which purpose I so shape the edge at that end that the portion 4 starts near the corner on an angular line towards the center of the card,

while the'inturned portion projects beyond this angularline to form a guiding ear 8 for the sheet.

The sheet 10 as before stated is of a thin,"

flexible material. It has turned-over longlb 'tudinal edges 11 so that it may embrace t e inturned edges of the frame and be slid into place longitudinally. The relatively sharp turns of the edges of the sheet and frame provide a means for holding the sheet taut transversely, but do not prevent its longitudinal removal or replacement.

In the modification of Fig. 3, the edges 12 of the frame receive but one inward turnupon itself, each fold of which passes around position.

ble stencil sheet therefor and means for holdbeing adapted-toresist pull. at right angles to- .comprising a fold: 'in I the card" and means adapted to prevent the unfolding of the card 30 of the frame and sheet, without injuring said sheets. It is the acute folds of the sheet the inturned edge of the frame, with the angle of the fold against the true edge of the frame, that causesit to be held in place without e5:- traneous clamping means being necessary, and in fact I prefer not to use clamping means, depending upon the folds of the sheet around 'the edge to give the thin, flexible sheet its tautness and rigidity in use. It will be seen that the fold of the stencil frame where it embraces or receives the folded edge of thecard acts as a means for preserving or maintaining the fold of .the flexible card without 'in anywise preventing its longitudinal removal or replacement.

What I claim as my invention is: 1. A stencil card frame, a removable flexible stencil card therefor and means for holding said card taut in said frame, said-means the edge ofthe card which is held and non resisting against longitudinal pull, said means by pull at right angles.

2. The combinationtfof removable exible;-,'stencil }sheet ;jhaving ,a folded edge, the fold ofthe 's'heet embracing saidedge'in the frame whenthe sheet is in 3. A stencil card frame, a removable flexiing said sheet taut in said frame, said frame having an inturned edge forming a bight, a fold of the sheet embracing said edge when. the sheet is in position, said inturned'edge being folded "upon itself so that it. extends into a'bight of the frame, and saidsheet in embracing said edge passing into the bight and around the edge. 4. A stencil card frame having an inturned edge, in combination with a removable stencil sheet of flexible material also hm ing an inturned edge, said edges of frame and sheet being hooked upon eachother whereby the sheet will be held taut.-

A stencil card frame having an in- .a aaant' ja i frame havin a fold its edge, a lengthwise turned edge, in combination with a removable stencil sheet of flexible material also having an inturned edge, said edges of frame and sheet being hooked upon each other whereby the sheet w ill be heldtaut, an abutment'at the end'of the frame to receive one end of the sheet as it is slid into place. 6Q

6. A stencil card frame having an inturned edge, in combination with a remov. able stencil sheet of flexible material also having an inturned edge, said edges of frame and sheet'being hooked upon each other whereby the sheet will be held taut, said inturned edge of the frame beginning near the corner of the card and strrting angularly therefrom tow: rds the center of the crrd.

7. A stencil 05rd frame having an in- 7 turned edge, in combination with a rentovable stencil sheet of flexible material also h.- ving an inturned edge, ssid edges of frame and sheet being hooked u on each other whereby the 'sheet will be he d taut, said in- 7.5 turned edge of theframe beginning near the corner of the card and starting angularly therefrom towards thec'enter of the card, and a projecting ear for theedge which ex-. tends beyond the-angular line thus formed. .80

8. A stencil card frame, a removable flexible stencil sheet thereforiand means for holding said sheet/taut in said frame, said frame having opposite inturned edges, and a fold n each opposite side of the sheet em-.- bracing an ed e when the sheet is in position.

9. A stenci card frame, a removable flexible stencil sheet therefor and means for 1 "holding said sheettaut in said frame, said r frame having inturned edges on opposite sides forming bights, and on each 0}) osite side of the sheet a fold embracing sai edge when the sheet is in position, said inturned edge being folded upon itself sothat it extends into 'a bight of the framejand said sheet in embracing said edge passing into the bight and around the edge.

10. .A stencil card frame having 0 posite inturned edges, in combination wit- 1 a removable stencil sheet of flexible material also having opposite inturned edges, said edges of frame and sheet being hooked upon each other whereby the sheet will be held taut.
